Hi - this is a brand new thing for WA state. It should be available through any of the IRS Free File options that include state returns. It's also available through VITA and probably AARP Tax-Aide, although I haven't confirmed that.

I am a VITA volunteer in the Seattle area and we are still learning about this credit.

This should be available through IRS Free File software options as well. TurboTax is not listed as one of the software options for this.

Yes, this is a brand new credit and you need to file a simple state form to claim it. If your income is less than $73k, use one of the options through IRS Free File that includes state returns for free:

I'm a volunteer with VITA, a free tax preparation program and we can also e-file both the federal and state returns for free. You can look up the closest location to you here:

Because this is so new we still are learning what is required for this credit. From what I understand you should include your state driver's license information and if you have children they need to be listed on the state form. You also need to answer a couple questions about residency (must have been a WA state resident for at least 183 days in 2022). There are some optional demographic questions.

You can find a list of supported tax filing software here; most of them have options through the IRS Free File program, so look there for free state returns.
